Be it known--that I, GEORGE residing at Stonington, in the county of certain new and useful Improvements in lVreck-IndicatingDevices, of which the fol.-

, lowing is a specification,

- relation more particularly reference being had to the accompanying drawings.

This invention relates to certain improvements in wreck indicating to a device of this general character especially designed and adapted for use in connection with submarines; and it is an object of the invention to provide a device of this general character having novel and improved means whereby the indicating medium affords a means whereby a flexible tube may be brought to,

the surface for the purpose of delivering air communication may pants of saidvessel;

.The invention consists in the details of constructionand in thecombination and arjrangement of the several parts of my improved wreck indicating device whereby cer- I cover 2, the

tain important advantages are attained and the device is rendered simpler, lcssexpensive and otherwise more convenient and advantageous for use, all as will be hereinafter more fully set forth.

'The novel features of the invention will;

be carefully defined in the appended claim. In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- I 1 Figure l is a sectional view illustrating wreck indicating device cordance with an embodiment of my invention; Fig. 2 is a sectional view taken sub sta'ntially at right angles to that in Fig. 1, with certain parts of the invention omitted;

and Fig. 3 1s atransverse sectional View" taken through the flexible tubing.

As disclosed in the accompanying drawings. H denotes a fragment of an upper portion of thehull of a submarine or other ves 'sel to-which is suitably secured the, casing 1 having coacting therewith .the removable rovided w th an upstanding extension 3 substantially cone shape in: form whereby a I maximum of .buoyancy is afforded to the cover member when released so that the same Specification of Letters Patent.

will readily riseto the surface of the water and the extension 3 projects'abovesaid surface so that the floatin cover may be readily discerned. Depen ing from the cover member 2 at substantially the axial center thereof and extending within the casing is the interiorly threaded sleeve {2 with which is detachably engaged in a conventional manmer the screw member 5 extending through the hull andin swivel engagement therewith, as indicated at G, in any desired manner, and the inner extremity of the screw is provided with the operating means 7 whereby the screw be readilyfdisengaged from the sleeve 4 when desired by an occupant of the boat.

Rotatablysupported within thecasing is a flanged drum 8 having produced at a predetermined point intermediate its length the depression or pocket 9 to accommodate the member 10, herein disclosed as airing-0f conventional diameter, towhich is secured an extremity of the flexible member 11, the opposite extremity of said member 11 being suitably secured to the under surface of the cover or closure member-"'12. The-flexible member is also 14 carried by the cap tachable engagement with an extremity of the flexible tubing .16, more particularly referred to, and it is to be observed that the diameter of the ring 10 is in-excess of the diameter of the ring 14:. By this arrangement, it will be perceived that upon release of the closure member or cover 2, the same will rise to the surface of the water and by pulling up the flexible member 11, the flexible tubing 16 may also be brought to the surface through the coaction between the rings 10and 14:, as is, it is thought, clearly apparent to those skilled in the art to which my invention appertains.

The flexible tubing 16 is normally wound I around the flanged drum 17 rotatably sup ported by the rigid tubular member orpipe compartments and the bore of the conduit to be hereinafter disposed through the ring l 15 normally in de-' ioo or pipe 18 is divided into two passages with which the compartments of the flexible tub- "ing 16 separately communicate. duit or pipe 18 at a I The conpoint intermediate the drum 17 is )rovided with a con lin 20' l P b conductors 22 extending within the boat and adapted to have their 1nner extremities suitn ably secured to a telephone instrument while the opposite or outer extremities are adapted to be suitably connected with :a telephone instrument in the possession of the rescue party. As herein disclosed, the heads of the,

drum 1? are connected by the spaced members 23 also spaced relative to the tubular member or pipe 18 whereby it will-be perceived that the tubing 16 may be readily wound upon the drum without interference or obstruction being offered by the coupling 20. It is also to be observed thatthe mar ginal portions of the cover 2 and the exten sion 3 are provided with the depending flanges 24 adapted to receive therebetween the upper marginal portions of the casing l to afford an effective engagement of the cover with the casing.

From the foregoing description, it is thought to be obvious that a wreck indicating device constructed in accordance with my invention is of an extremely simple and.

comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice.

I chum: In combination Wltll a body, a casing se cured thereto exteriorly thereof and having its outer face open, a cover for the open face of the casing, an upstanding extenslon substantially cone-shaped in form secured to the cover, the marginal portions of the extension and the cover being provided with flanges disposed inparall'el spaced relation, adapted .to receive the marginal portions of the open end of the casing therebetween, :1 depending interiorly threaded sleeve carried by the cover member at substantially the axial center thereof, a screw member extending through the body and in suitable engagement therewith. the outer extremity of the screw member being capable of threaded eng' gement with the depending sleeve of the, cover 'member, and means for rotating said screw member.

In testimony whereof I hereunto atlix my signature in the presence of two witnesses.

GEORGE W. HEATH.
